The centrist camp of French President Emmanuel Macron is not guaranteed to win an absolute majority in this month's legislative elections, two polls showed on Tuesday.

Macron won a second mandate in April as France's centrist, pro-European president however, he also needs to win a majority in the lower house of parliament in the June 12 and 19 ballot to be able to implement his reform agenda.

According to a poll by the IFOP institute for broadcaster LCI,  Macron's Renaissance party and allies could win as little as 250-290 seats, although the absolute majority is at 289 seat. 

Last week, Macron's party and its allies won 275-310 seats according to the same pollster. 

Harris Interactive - Toluna poll for Challenges magazine on Tuesday had a more optimistic forecast of 285-335 seats for Macron's camp, but there too it could be short of an outright majority.

Macron's La Republique en Marche party single-handedly won 314 seats in the 2017 legislative elections but gradually lost lawmakers to stand at just under 270 now.
